WEATHER STRIP.

Application fled larch 15, 1926. .Serial No. seaao The invention relatesto improvementsin weather strips designed for use upon 1nwardly swlngingcasement windows and the v a movable strip is swun after described andclaimed, the description being supplemented by the accompanying drawing.1 Figure 1 is a perspective view of a casement window equipped with myinvention. Figures 2 and 3 are vertical sectional views, partly in'elevation, showing the manner of operationof the movable strip.

Figure 4 is an additional sectional view out in a different plane fromFigures 2 and 3 and showing the spring which constantly exerts a liftingforce .on the movable strip, so as to raise'it to inoperativeposition'as soon as permitted to function in this manner.

Figure 5 is a perspectiveview of the device disconnected from the sash.

In the. drawing above brieflydescribed, 6 designates the sill of a)casement window and the numeral 7 designates two inwardly swingingsashes. A head 8, preferably formed from a' single metal plate, asshown, is secured upon the sill 6 and extends throughout the lengththereof, and the lower 'edge of each sash 7 is rovided with alongitudinal recess 9 whic extends throughout the length of said edgeand opens to the outer, side of the sash, but not through the inner sidethereof, the sash beingformed with a groove 10 in the angle between theupper and-inner wallstof the recess 9.'

in Figures and 4 when the sash is closed. The strip isformed from asingle elongated piece of sheet metal having one edge rolled to providea tubular head 12, said bead having relatively small notches 13 near itsends and 'a r notch 14 between its ends. Bearings 15, preferably formedby bending metal strips at one end, positioned in the notches 13, whilea coiled torsion spring 16 isdisposedinthenotchlL-Arodflpasses whi w llexclude. may

any possibility the notches 13 and 14, said rod passing entirely throughthe tubular head 12 and through the bearings L5 and throu h the i 7spring 16. An eye 18 at the angle 0 a bell crank 19, is positioned onone end of the rod 17 and is received in a notch 20 in one extremity ofthe tubular bead 12, one arm 21 of said bell crank being secured to thestrip 11. while the other arm 22, is adapted for ooaction with the head8 to swing said strip 11 downwardly against the action of the spring I16, when the sash is closed;

When mounting the device in the recess f), the metal strips 23 fromwhich the bearmgs 15 are bent, are secured by suitable fasteners 24 tothe inner wall of said recess 9, the tubular head 12 and the partslocated in its notches, then extending into the groove 10, so that theportion of the sash at the other side of this groove, forms a watershed, preventing any water from entering above the strip 11. When thedevice is so applied, one end 25 of the spring 16 bears against thelower side of the strip 11 and the otherfend 26 of said spring, engagesthe inner wallbf the recess-9. Thus, the spring has a constant tendencyto raise the weather strip 11 to the horizontal position shown in Figure2, in which position it will clear the head 8. When the strip ispositioned in this manner the arm-22 projects downwardl so as to strikethe bead 8 when the sas is closed, thereby swinging the bell crank 19and moving-the strip 11 downwardly to the outwardly declinedposition-shown in Figures 3 and 4, in which position it: willefiectively prevent entrance of water, snow, sleet, wind, etc. Assoon-as the sash is opened,

the pressure of the head 8 against the arm 22 is relieved, vallowing thespring 16 to swing the" strip 11 -upwardly, so that the sash may beeasily opened.

Attention isinvitedto the fact that the bead 8 constitutes avstationary.weather stop A movable weather stripll is provided to outwardly eclineover the'bead 8 as shown means16tocomeintop y permits the spring for thepurpose such of raisin the movable weather stop 11, clear of t e bead 8.Attention is also invited toithe fact that while the weather stop 11 andassociated parts are preferably mounted in a recess such as 9,constituting a water shed, a shed of any other adequate form could beprovided.

The invention is exceptionally simple and inexpensive yet will beefiicient and in every.

wa desirable. The results have been excel ent from the details disclosedand they are therefore preferably followed, but w1th-. in the scope ofthe invention as clalmed, variations may be made.

I claim; p i g 1. A weather seal adapted for mounting on acasementwindow sash for coaction' with an upstanding sill carried bead extendingthroughout the length of the sill and projecting above the sill to forma water stop, said seal comprising an elongated metal 7 strip having atubular bead alon one of its is adapted to coaction with thesill-carried longitudinal edges, said bead belng formed near itsends'with notches, having another notch at one of its ends, and beingformed with an. additional notch between its ends,

bearings in the notches near the ends of said bead having attachingmeans for anchorage to the sash, a coiled torsion spring in the notchbetween the ends of the bead, one end of said s ring engaging the stripwhile the other"end v sash, a rod passing loosely throught e en-- tirelength of said tubular bead and spanning all of its notches, said rodpassing throu h said bearings and said spring, and a bell crank having.an eye received-in" the notch at the end of said tubular bead, said eyebeing mounted on one extremity of. said rod, one arm of said bell crankbeing secured to said strip while the other arm thereof bead to offsetlowering of the strip against the action of the aforesaid spring.

2. A weather seal for a'casement window sash, said sash having in itslower edge a longitudinal recess extending throughout the length of saidedge and opening to the outer side of the sash and having a longitudinalgroove in the anglle between the upper and inner walls of t e recess,said walls and groove forming a, water shed, said seal comthereof isadapted to enga e the,

prising an elongated sill-carriedbe'ad formed from a single strip ofmetal bent longitudinally 'upon it'self to form an upstanding portionand havin its opposite edge bent laterally to form, anges for attachmentto the'sill, an- 'elongated sealing strip having a tubular bead alongits upper longitudinal edge, said bead havinga plurality of notches, arod passing throughv. said bead, bearing members arranged in certain ofsaid notches secured to said strip while-the other arm thereof isadapted forco action with the.

sill carried bead to efl'ect the lowering of the sealing strip when thesash is closed.

- 3. An inwardly opening casement window sash having a water-shedthroughout the width of its lower end, a weather stop ex-' tendinglongitudinally undersaid' water shed and piv ted to the sash formovement from an out ardly declined normal positron to, a raisedinoperative position, a statlonary weather stop bead extendinglongitudinally of the window -sill, said head being normally disposedunder the. upper portion of said. weather stop, spring meansacting onsaid weather stop and tending to raise it'clear of the bead, and an armcon nected with said wather'stop and normally .abutting the inner sideof said bead to retam said weather stop in its-normal position againstthe action of said spring means, said ar m moving away from said beadand per mltting raising of said weather stop by said spring means as thesash is opened, said,

arm upon closing of the sash coming again into contact with the bead toagain swing v the weather stop downwardly to operative whereof I havehereunto .affixedmy signature. v

position.
